Summary: This study investigated the contagion effects of exposure to others' confided suicidal thoughts among adolescents and identified related risk and protective factors. The study found that adolescents with recent exposure to others' suicidal thoughts were more likely to engage in self-harm and exhibit suicidal ideation and plans within one month. The risk was highest when the exposure came from parents. Support from parents and teachers could protect adolescents from the impact of contagion.

Summary: This research examines the genomics and in vivo dynamics of family context and experienced affect following discharge from psychiatric hospitalization for suicidal thoughts and behaviors. The study involves a longitudinal, multimethod observational investigation and participants are recruited from an inpatient child and adolescent psychiatric hospital. The research protocol aims to characterize the in vivo, real-world experienced affect and observed family context associated with STB in adolescents during the high-risk weeks post discharge, merging multiple fields of study.

Summary: This study aimed to explore why young people communicate online about self-harm and the perceived benefits and harms of these communications. The findings show that young people engage in online communication about self-harm because they are unable or unwilling to speak about their experiences offline. Online spaces provide anonymity and peer support, which can have both positive and negative effects. Additionally, individual, social, and systematic factors influence perceptions of online self-harm communication.

Summary: The study examined the association between social media use and self-injurious behaviors in adolescents hospitalized in a psychiatric unit. Adolescents with documented social media use had increased odds of self-injurious behaviors, suggesting a potential marker of impulsivity. Further research is needed to incorporate assessment of social media use into routine adolescent psychiatric evaluations.

Summary: This study investigated the factors associated with suicidality related to the COVID-19 lockdown in Romanian adults. The results showed a strong correlation between anxiety, depression, and suicidality. However, the impact of internet use and belief in conspiracy theories on suicidality was not significant. Younger age, emotional disturbances, and previous life-threatening attempts were identified as significant predictors for suicidality.

Summary: Previous studies have shown that psychotic experiences are associated with an increased risk of suicidality. However, it is unclear whether this association is causal or arises from shared risk factors. Furthermore, little is known about the association between psychotic experiences and non-suicidal self-injury (NSSI).

Summary: The use of photograph-based social media among children and adolescents has raised concerns about self-confidence and behavior, particularly related to potentially dangerous trends that can harm the skin. Pediatricians should stay informed on social media trends in this age group and be vigilant for cutaneous findings that may indicate risky behavior on social media.

Summary: Adolescence is a challenging stage where there is a risk of developing disorders. A non-random sample of 563 high school students from public schools in Mexico was studied, with 32.8% males and 67.14% females. The results showed that 73.3% of the adolescents did not engage in self-injurious behavior, while 26.4% did. Factors such as depression and first sexual experience were found to have a strong relationship with self-injurious behavior. It was concluded that early detection of self-injurious behavior can prevent further harm and suicide attempts.

Summary: Depressive disorders are a major challenge to public health worldwide, requiring effective prevention and management strategies. Suicidal tendencies often occur during depressive episodes, making it a significant global health concern that demands effective preventive strategies. Current psychiatric approaches primarily rely on medication but have limited success in addressing the global burden of mental health issues.

Summary: Self-inflicted damage to the retina using handheld lasers is a growing and underrecognized form of self-harm, which can ultimately result in legal blindness. Patients with histories of major depressive disorder and self-harm behaviors are more susceptible to this type of harm. Mental health providers should be vigilant in screening for laser pointer access and preventing permanent vision loss in at-risk individuals.

Summary: This study adapted the Mood Rhythm Instrument (MRhI) into the MRhI-Y to assess and evaluate perceived mood-related symptoms in adolescents. Through three steps of adaptation, expert review, and pilot testing, the final questionnaire MRhI-Y was developed for the adolescent population. The MRhI-Y demonstrated good internal consistency and a three-factor solution through exploratory factor analysis. The findings revealed that younger adolescents reported lower rhythmicity scores compared to older groups.

Summary: In this study, the researchers aimed to develop algorithms for accurately detecting nonwear in wrist-actimetry data and identify useful variables in the process. They compared different solutions for detecting off-wrist and found that automated strategies were similarly effective to visual inspection but faster and less reliant on raters' attention/experience. However, all methods had limitations in detecting short intervals.

Summary: This study aimed to evaluate the potential predictors of adequate treatment response in MDD, including sleep, levels of 6-sulfatoxymelatonin, and other circadian parameters derived from actimetry. The results showed that increased activity levels, earlier peak of activity, and lower intradaily variability of light exposure were associated with early antidepressant response. Sleep parameters and 6-sulfatoxymelatonin levels did not predict treatment response.

Summary: The study found that late chronotypes and higher social jetlag (SJL) are associated with a higher prevalence of smoking. There are two potential scenarios explaining the smoking-SJL association: (A) If smoking delays the biological clock, quitting smoking should advance the circadian phase. (B) If people smoke more to compensate for the consequences of SJL, quitting smoking should not change the circadian phase. Monitoring participants of a smoking cessation program, the results showed no effects of cessation on SJL, chronotype, sleep quality, or daytime sleepiness, favoring scenario (B). Therefore, smoking may be a consequence rather than a cause of SJL. Daytime sleepiness was a significant predictor in the study but did not improve with cessation.

Summary: This study investigates the association between cognitive reappraisal and panic disorder (PD), and finds that PD patients have weakened functional connectivity between the prefrontal cortex (PFC) and the amygdala, which is associated with the severity of PD symptoms. Additionally, cognitive reappraisal is negatively correlated with PD severity, and the PFC-amygdala functional connectivity plays a mediating role in this association.

The study utilized network analysis to examine the symptom dimension of depression and anxiety in different age groups of adolescents. The results indicated that different age groups have different key symptoms and bridging symptoms, highlighting the importance of targeting specific symptoms at different stages of adolescence in treatment to alleviate the comorbidity of anxiety and depression.

Summary: Screening for psychological distress in adolescents is important, and the Distress Questionnaire-5 (DQ5) is a reliable measure for this purpose. The study found that DQ5 had good fit to a unidimensional construct, strong criterion and predictive validity, and sensitivity to change. The brevity and ease of interpretation of DQ5 make it suitable for screening in schools.

Summary: Major depressive disorder is a prevalent condition worldwide, but the proportion of patients receiving treatment has not increased. Biomarkers related to drug-treatment responses can be used to monitor the effectiveness of medication. Serum protein levels were compared among patients with depression who received medication, those who did not, and a control group. Eight biomarkers were identified, which can be used to monitor the effectiveness of drug treatment.
